Re: 132 Columns...

[Scott Klement <tn5250@xxxxxxxxxxxxxxxx>]

Hi Fred,

You say that you don't want to use xt5250 or X11 -- but you don't say 
what you DO want to use, so it's hard to offer suggestions.  I'm going 
to assume that you're running this in console mode?

The font_80 and font_132 config keywords tell TN5250 to send an escape 
sequence that tells the 'xterm' program included in X11 to change it's 
font.  They won't have any impact whatsoever in console mode.

The fonts, including the number of rows and columns available, in 
console mode tend to be implemented in hardware, and which ones are 
available depends heavily on your video card, and how well that video 
card is supported by your kernel's console driver.   My experience is 
that all video cards today support 80x25 mode and very little else, 
since they all expect to be used by Windows or X11 where everything is 
rendered in raster graphics anyway, and therefore it makes little sense 
to spend money on providing lots of different text modes.

That doesn't mean that 132 columns aren't possible... they may be.  But 
you'll need to write a shell script that sets the console to at least 
132 columns and at least 28 rows.  In FreeBSD, there's a utility called 
'vidcontrol' that you could attempt to use in a script...   I'm not 
familiar enough with OpenBSD or NetBSD to tell you if it has the same 
utility or different one.

Once you've provided a display with enough rows and columns, you should 
be able to simply call TN5250 with env.TERM set to IBM-3477-FC, and it 
should work.  Though, honestly, I haven't tried it because none of the 
video cards I use for BSD have support for 132 columns in console mode.
